    A diagram in Ignace-Gaston Pardies's objections to Isaac Newton's theory of light and colour, in a letter to Henry Oldenburg dated 3 April 1672 (EL/P1/75/003).

Both letters were read at the meeting of the Royal Society on 18 April 1672, and published in Philosophical Transactions of the Royal Society, vol. 7, no. 84 (June 1672).
